Abstract

The utility model relates to a telescopic support for placing concrete floor, comprising inner and outer two steel tubes which are sheathed together. The lower end of the outer tube and the upper end of the inner tube are respectively provided with end panels which are vertical to the shaft lines of the tubes. The end panels are provided with connecting holes, and the inner tube wall is uniformly provided with radial through holes along the length direction of the inner tube. The upper segment tube wall of the outer tube is provided with external threads, and the external threads are screwed with a nut. The upper segment tube wall of the outer tube, which is provided with the external threads, is provided with a radial long strip through hole along the length direction of the outer tube. The length of the long strip through hole is the sum of the distances of the adjacent holes of the inner tube wall and the diameters of the through holes. The radial through holes of the inner tube wall and the outer tube wall are penetrated with pin rods. The length of the pin rod is equal to or a bit longer than the external diameter of the nut. The utility model replaces wood with steel as the support, protecting wood materials with no wood be consumed, being favorable to the ecological balance of human's livingenvironment. The utility model has consistent shape, adjustable length, suitable use in constructional floors of different heights, and convenient supporting, being able to be recycled to use, with reduced constructional cost, strong intensity and safe use.

Description

Concrete floor cast telescopic prop

Technical field

The utility model relates to a kind of concrete floor cast telescopic prop.

Background technology

The floor of each interlayer of building is in the concrete pouring of scene, building site.In the prior art, when the fluid concrete floor, do the cast of shore supports template with rod mostly, make pillar, consume a large amount of timber with rod, because each interfloor height of building is not quite similar, rod is difficult for recycling, and the expense of construction is improved, and uses timber in a large number, waste the forest reserves, be unfavorable for the ecological homeostasis of human habitat; The shape of rod is not the same, props up immediately also inconvenience at the scene, and the intensity of rod neither be very big, also can cause danger sometimes.

Summary of the invention

The purpose of this utility model is in order to overcome above-mentioned deficiency, to propose a kind of shape unanimity made from steel pipe, at the scene Zhi Lifang just, the concrete floor cast telescopic prop that intensity is big.

The utility model is realized with the following method.

Concrete floor cast with telescopic prop have being nested together of matching in, outer two steel pipes, the lower end of outer tube and the upper end of interior pipe have end plates respectively, the axis of end plates and pipe is perpendicular, the connecting hole that matches is arranged on the end plates, on the tube wall of interior pipe, length direction along interior pipe is evenly equipped with radial direction through hole, on the epimere tube wall of outer tube external screw thread is arranged, be rotary with nut on the external screw thread, have on the externally threaded epimere tube wall at outer tube, radially strip through hole along the outer tube length direction is arranged, the length of strip through hole be on the inner tubal wall adjacent radial through-hole spacing from an inner tubal wall on the through-hole diameter sum, be installed with pin rod in the radial direction through hole on radially strip through hole on the outer tube wall and the inner tubal wall, the length of pin rod is equal to or slightly greater than the external diameter of nut.

On the tube wall of pipe and outer tube radial direction through hole is arranged in of the present utility model, can be installed with in the radial direction through hole and connect pin rod and interior pipe and outer tube are coupled together become concrete floor and pour into a mould and use telescopic prop, be evenly equipped with a plurality of radial direction through hole on the tube wall of interior pipe, some through holes on the selection inner tubal wall communicate with the strip through hole on the outer tube wall and penetrate pin rod, the adjustable concrete floor cast length of telescopic prop, swivel nut promotes the pin rod in the through hole, can finely tune the length of concrete floor cast with telescopic prop.

During use, look the distance of the upper and lower interlayer of construction building, the different through holes that connect inner and outer pipe with pin rod are regulated the length of concrete floor cast with telescopic prop, concrete floor cast propped up with telescopic prop stand in the upper and lower interlayer of building and be used for support shuttering, the slight distance of upper and lower interlayer can be regulated by swivel nut.

The utility model for the carpentery workshop pillar, does not consume timber with steel, has protected the forest reserves, helps the ecological homeostasis of human habitat; Length of the present utility model can be regulated, can be suitable in the construction floor of differing heights, using, shape unanimity of the present utility model, prop up very convenient immediately at the scene, use up easily recycling of back, can reduce operating expenses, the utility model is to make with steel, intensity is bigger, and is safe in utilization.

Below in conjunction with accompanying drawing, the utility model is further described.
